What does a millimeter water (4°C) measure?

It represents the hydrostatic pressure from a 1 mm column of pure water at 4 °C under standard gravity, used for measuring very low pressures.

What is a petapascal used for?

The petapascal is applied to quantify extremely high pressures, such as those found in high-energy physics experiments and astrophysical environments.

Why does converting from millimeter water (4°C) to petapascal result in very small numbers?

Because millimeter water (4°C) measures tiny pressures while petapascal represents tremendously large pressures, leading to conversion values that are numerically extremely small.
